Store Scraped Data in JSON Format
Explore how to store web scraped data using Puppeteer in JSON format. Understand the benefits of JSON including its use in web development, APIs, and NoSQL databases. Learn to create JSON objects or arrays, convert them to strings, and write them to files. This lesson guides you through practical coding examples and best practices to ensure your scraped data is structured, accessible, and ready for further use or analysis.
We'll cover the following...
After successfully scraping data using Puppeteer, storing the extracted information is essential for further analysis or use in other applications. One popular and versatile data format for storing structured data is JSON (JavaScript Object Notation). In this lesson, we’ll learn how to store scraped data using Puppeteer in JSON format.
JSON overview
JSON is a lightweight, human-readable data interchange format widely used for storing and exchanging data. It represents data in a key-value format, allowing for nested structures and arrays. JSON supports various data types, including strings, numbers, boolean, objects, and arrays. JSON is easy to parse and generate, making it an ideal choice for storing structured data. We can access an element in a JSON object using its key.
The code snippet below shows how to define a JSON object and access the title’s value using the appropriate key.

When to use JSON
Here are some situations where using JSON for exporting scraped data is advantageous.
Web development: JSON is particularly useful in web development, where JavaScript code can directly consume it. If we use the scraped data in a web ...
